Abstract

Curvularia species are associated with a wide range of ecological roles, functioning as pathogens of plants, animals, and humans, as well as occurring as epiphytes, saprophytes, or endophytes, predominantly on cultivated cereals. In this study, two putative isolates of the genus Curvularia were collected from leaves of Setaria sp. and Sorghum sp. in Rasht County, Guilan Province, Iran. Multi-locus phylogenetic analyses based on ITS, GAPDH, and TEF1 sequences clustered the studied isolates in a well-supported lineage together with ex-type and representative strains of Curvularia austriaca. This species, previously known only as a human pathogen, is recorded for the first time from Iran. This study expands the known geographic distribution of C. austriaca, and reports Setaria sp. and Sorghum sp. as novel hosts worldwide, highlighting the importance of integrative morphological and molecular approaches for accurate species identification in Curvularia.
